Supporting structure for a figure-form candle lamp

Abstract

Disclosed is a supporting structure associated with a base of a candle lamp for internally reenforcing a plastic figure-form shell of the candle lamp. The supporting structure includes a long hollow tubular member and a sleeve member. The tubular member has an enlarged top portion for receiving a lamp socket therein and a lower end for inserting into an upper portion of the sleeve member. The sleeve member has a lower connecting portion for associating with a lamp base. Thereby, a plastic figure-form shell of the candle lamp can be put over the supporting structure without easily becoming deformed or bent after assembly.

What is claimed is: 
     
       1. A supporting structure for internally reenforcing a plastic figure-form candle lamp, comprising: a base;   a sleeve member having a lower connecting portion for engaging said base, an upper hollow tubular portion, and a middle enlarged retaining portion between said upper hollow tubular portion and said lower connecting portion;   a long hollow tubular member being made of hard plastic material for electrical wires to pass therethrough, said long hollow tubular member having an attached pair of symmetrical halves, said attached pair of symmetrical halves having a lower end engaged with said upper hollow tubular portion of said sleeve member and an enlarged upper end defining a room; and   a lamp socket being mounted in said room defined by said enlarged upper end of said attached pair of symmetrical halves and being provided with an inner wall surface with threads for a bulb to screw thereinto, said lamp socket having two conductive plates disposed therein to connect with said wires and thereby forming an electrical connection with two electrodes of the bulb.   
     
     
       2. A supporting structure as claimed in claim 1, wherein said symmetrical halves forming said long tubular member have along their joining edges a plurality of complementary projected blocks and recesses whereby said plurality of projected blocks engage said plurality of recesses to connect said symmetrical halves together. 
     
     
       3. A supporting structure for internally reenforcing a plastic figure-form candle lamp, comprising: a base;   a sleeve member having a lower connecting portion for engaging said base, an upper hollow tubular portion, and a middle enlarged retaining portion between said upper hollow tubular portion and said lower connecting portion;   a long hollow tubular member being made of hard plastic material for electrical wires to pass therethrough, said long hollow tubular member having a lower end engaged with said upper hollow tubular portion of said sleeve member and an enlarged upper end defining a room; and   a lamp socket being mounted in said room defined by said enlarged upper end of said long hollow tubular member and being provided with an inner wall surface with threads for a bulb to screw thereinto, said lamp socket having two conductive plates disposed therein to connect with said wires and a cylindrical body, said conductive plates forming an electrical connection with two electrodes of the bulb, and said cylindrical body engages said room of said enlarged upper end of said long hollow tubular member and having a lower cap attached to a bottom of said cylindrical body.   
     
     
       4. A supporting structure as claimed in claim 3, wherein said lower cap includes a bottom plate on which two oppositely located retaining wings are formed, said retaining wings engaging an inward extended flange formed on said bottom of said cylindrical body to attach said lower cap to said cylindrical body. 
     
     
       5. A supporting structure as claimed in claim 4, wherein said cylindrical body is provided at an inner wall surface with two vertically extended long recesses to each receive one of said conductive plates. 
     
     
       6. A supporting structure as claimed in claim 5, wherein said cylindrical body has a crossbar disposed therein near a lower portion thereof to separate said two conductive plates from each other and together with said lower cap hold said wires in place. 
     
     
       7. A supporting structure as claimed in claim 6, wherein said two conductive plates are fixed into said vertical recesses and each has a pointed lower end to pierce through an insulation skin of one of said wires restricted in place by said lower cap and said crossbar to form an electrical connection. 
     
     
       8. A supporting structure for internally reenforcing a plastic figure-form candle lamp, comprising: a base having a receiving hole, said receiving hole having an inner peripheral wall with a projected block;   a sleeve member having a lower connecting portion for engaging said base, an upper hollow tubular portion, and a middle enlarged retaining portion between said upper hollow tubular portion and said lower connecting portion, said lower connecting portion has a lower end having a half-arrow-shaped cross section and a groove in an outer peripheral wall to engage said projected block of said base;   a long hollow tubular member being made of hard plastic material for electrical wires to pass therethrough, said long hollow tubular member having a lower end engaged with said upper hollow tubular portion of said sleeve member and an enlarged upper end defining a room; and   a lamp socket being mounted in said room defined by said enlarged upper end of said long hollow tubular member and being provided with an inner wall surface with threads for a bulb to screw thereinto, said lamp socket having two conductive plates disposed therein to connect with said wires and thereby forming an electrical connection with two electrodes of the bulb.
